GENERAL DESCRIPTION

The ADV7175/ADV7176 is an integrated digital video encoder that converts Digital CCIR-601 4:2:2 component video data into a standard analog baseband television signal compatible with world wide standards NTSC, PAL B/D/G/H/I, PAL M or PAL N. In addition to the composite output signal, there is the facility to output S-VHS Y/C video, YUV or RGB video. The Y/C, YUV or RGB format is simultaneously available at the analog outputs with the composite video signal. Each analog output generates a standard video-level signal into a doubly terminated 75 Ω load.
